True or False? The 7mm-08 is virtually identical to the cartridge that the M1 Garand was originally designed to shoot.

I'm thinkin true.

It's based on a .308 I guess false.

Who was instrumental in insisting that .30 caliber was the minimun caliber necessary for military needs, thereby killing every contender but the otsix?

Douglas MacArthur. He probably was concerned about the number of Springfields and 1917s still in service, the amount of 30-06 ammo warehoused, and the logistics of not only moving to a new battle rifle, but a new cartridge as well.

If the 276 had been adopted it would probably still be our standard rifle round.

You can still put a lot more 5.56 into a train car, air drop, or on a soldier than any full power round.

Those that throw the most bullets tend to win the war.

German and Japanese aircraft used 20mm which much had greater range and hitting power, but the US used larger amounts of .50.
